Computed tomography (CT) is a diagnostic method that uses X-rays to obtain cross-sectional images of the inside of the body.
The main elements of the CT scan are the X-ray tube and detectors which are suspended on opposite sides of a circular rim. The X-ray tube generates radiation that passes through the body of the patient lying inside the tomograph and is picked up by detectors. The beam of X-rays penetrating the body is absorbed to varying degrees by the tissues in the human body. The detectors are able to measure the level of absorption of X-rays and on this basis a section of the body is created. Bones, which absorb radiation most strongly, will be visible in white, and other tissues in various shades of gray.
Computed tomography is characterized by high spatial resolution. It is possible to obtain two- and three-dimensional images of the examined structures.
At the Carolina Medical Center, we use the Philips Brilliance CT 40.
